Pressure-sensitive adhesive sheet and method for producing the same

摘要

To provide a pressure-sensitive adhesive sheet that is free of swelling or deformation of a substrate due to migration of a liquid component from the pressure-sensitive adhesive layer and has acceptable processability, the pressure-sensitive adhesive sheet includes a carrier film; an elastomer film provided on one surface of the carrier film; and a pressure-sensitive adhesive layer provided on the elastomer film, in which the pressure-sensitive adhesive layer includes a composition that contains an acrylic polymer as a main component and a compatible component being compatible with the acrylic polymer and liquid or paste-like at room temperature, and in which the carrier film has a heat shrinkage of 3.0% or more and 4.5% or less in the longitudinal direction and 1.2% or more and 4.2% or less in the transverse direction.
